Festo
187339
Proportional pressure control valve MPPES-3-1/4-PU-PO-010
The Festo part number 187339 is an electrical, pilot-controlled piston control valve featuring a 3-way proportional pressure control valve closed design with a soft sealing principle and any mounting position. It operates within a DC operating voltage range of 18 V to 30 V, a nominal operating voltage DC of 24 V, and includes short-circuit and reverse polarity protection for all electrical connections. With an operating pressure of 12 bar (1.2 MPa), an inlet pressure range of 11 bar to 12 bar (1.1 MPa to 1.2 MPa), and a pressure regulation range of 0 bar to 10 bar (0 MPa to 1 MPa), the unit delivers a nominal width pressurization and exhaust nominal width of 7 mm, a max. pressure hysteresis of 0.05 bar (0.005 MPa), an on switching time of 200 ms, and a switching time off of 890 ms, incorporating safety instructions where the outlet pressure drops to 0 bar if the power supply cable breaks.
